The land degradation because of salinity and waterlogging is an international phenomenon, afflicting approximately 1000000000 hectares in the sovereign borders of at the very least seventy five international locations. along with watching the foodstuff safety, it has a long way attaining and unacceptable socio-economic effects considering a wide percentage of this land is inhabited by way of smallholder farmers. The anthropogenic-environmental adjustments and the weather switch are extra including to the matter of salinity and waterlogging. The phenomenon of sea-level upward thrust will carry extra parts below waterlogged salinity because of inundation by way of sea water. hence, facing the salinity in truth is turning into a hugely hard activity as a result of its advanced nature, uncertainty and differential temporal and spatial affects. however, with the necessity to supply extra nutrition, feed, gasoline, fodder and fiber to the increasing inhabitants, and non-availability of latest effective land, there's a desire for productiveness enhancement of those lands. in truth, the salt-affected and waterlogged lands can't be missed due to the fact large investments were made during the global within the improvement of irrigation and drainage infrastructure. The social, financial and environmental expenditures being excessive for theon-and/off-farm reclamation recommendations, saline agriculture together with agroforestry inculcated with sleek leading edge concepts, is now rising as a possible device not just for arresting salinity and waterlogging yet for different environmental companies like mitigate weather swap, sequester carbon and biodiversity recovery. This book makes an attempt to handle a variety of concerns, rules and practices concerning the salinity thinking about rehabilitation of waterlogged saline soils and really apt use of saline waters together with sea water. a few of the web site particular case reviews regular to the saline setting together with coastal ecologies maintaining productiveness, rendering environmental companies, keeping biodiversity and mitigating weather swap were defined intimately. Written via top researchers and specialists in their personal fields, the ebook is a needs to, not just for salinity specialists but in addition for coverage makers, environmentalists, scholars and educationists alike. extra importantly, it contributes to reversing the salinity developments and teaches to maintain with salinity making sure the livelihood of resource-poor farming households leaving in harsh ecologies together with coastal parts that are extra susceptible to weather change.

Many halophytes have been evaluated for their potential use as crop plants and also for remedial measures (Dagar 1995b; Miyamoto et al. 1996; Barrett-Lennard 2003; Reddy et al. 2008; Ruan et al. 2008; Qadir et al. 2008; Yensen 2008; Flowers et al. 2010; Tomar et al. 2010; Rozema et al. 2013; Hasannuzzaman et al. 2014; Dagar et al. 2009, 2013, 2015c). Species such as Distichlis palmeri, Chenopodium quinoa, C. album, Pennisetum typhoides, Salicornia bigelovii, Diplotaxis tenuifolia and many others have been established as food crops, are being explored commercially and can be cultivated using sea water for irrigation.
2004), Gupta et al. 997). Many of the medicinal and aromatic underexplored crops are in great demand for both internal requirements and export. But since these crops are nonconventional in nature, it is not always feasible to produce these on fertile lands, which can be used for arable crops. The marginal lands, speciﬁcally the saltlands where proﬁtable returns are not possible from conventional crops, can successfully be utilized for the cultivation of these high-value crops with marginal inputs.
6 showing its potential at moderate alkali soil (Dagar et al. 2006a). Matricaria chamomilla, Catharanthus roseus and Chrysanthemum indicum were other interesting medicinal and ﬂower-yielding plants, which could be grown on moderate alkali soil (Dagar et al. 2009). All these crops can be blended suitably as intercrops in agroforestry systems. 6) than normal soil and is quite remunerative. 9 Mg haÀ1 could be obtained after 3 years of growth (Dagar et al. e. 6 lakhs haÀ1 per annum, and the soil was ameliorated in terms of reduction in pH and ESP and increase in organic carbon substantially.
